Sense-Making phase transition framework for Affect

Contemporary accounts of affect emphasize different perspectives, ranging from the regulation of bodily states in allostatic approaches to the relational and sense-making character stressed by enactive theories. Here, we show that affect can be made explicit within the sense-making phase transition framework previously introduced for the perception of an inner sensation. Within this same formal structure, each stable minimum of the sense-making potential defines an affective state: its position determines valence, while its depth determines arousal. Affect therefore is not introduced as an independent ingredient, but emerges as the associated state in the valence-arousal space, providing a link between allostatic and enactive approaches to affect. This formulation distinguishes valence intensity from arousal, allows for dominant and secondary affective states, and naturally accommodates mixed-valence configurations beyond a strictly bipolar description. Revisiting representative landscapes of the model, we show how neutral, uncertain, polarized, and mixed-valence regimes arise as a function of contextual sensory information, learned historical evaluation, and externally supplied information. We further show that the resulting valence-arousal relation provides a theoretical basis for the upper-open V-shaped organization discussed in the affect literature, while also opening a natural route toward a dynamical description of affect and emotions.

Spin-Based Modeling of Perception as Emergent from contextualized Internal Evaluation

We develop a microscopic model of perception of an interoceptive sensation in which spin-like variables encode an organism's internal evaluation of embodied vital norms associated with the sensation. Spins can take positive, negative, or neutral values. These local valorizations interact on a lattice embedded in the environmental context, and their collective configuration gives rise to a macroscopic perceptual state. By applying a coarse-graining procedure to a family of symmetric spin models, we derive a macroscopic Landau-type functional that makes explicit the mechanism by which key phenomenological features of perception, emerge from microscopic evaluative interactions. A central result is that the inclusion of a neutral evaluative state fundamentally alters the structure of the perceptual landscape, enhancing entropy, lowering the critical threshold, and increasing sensitivity to contextual input. These results establish a principled link between microscopic evaluative processes and large-scale perceptual organization, offering a flexible framework for integrating perceptual regulation and neurobiological modeling. The model integrates notions of neuroscience and cognitive science using the formalism of condensed matter field theory and providing novel theoretical insights and experimental predictions for conditions such as mental disorders and chronic pain.
